To all whom it-ma'y concern:-

-Be itknownthatwe, ALEXANDER WINTON and HAROLD B. ANDERSON, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Valve-Actuatin'g' Mechanism for Explosive-Engines, of which the following is c a specification, reference being had therein to-the accompanying drawing. 7

This invention relates to improvements in valve actuating-mechanism forexplosive enginesthe' rimary object of which lSiJO so arrange an construct the parts thatthevalves andstheir cooperating parts can be "readily and -independent-ly removed, and therefore readily accessible for inspection, repair or substitution.

In the accompanying drawing Figure '1 is aside elevation of a vertically arrangedexplosive engine, partly in section, with the present improvement applied thereto. Fig.

12 is an enlarged side elevation (partly insection) of-the outerends of the valve stems r and-the adjacent-cooperating parts. Fig. 3

is a detached side view of the valve stem yoke. "-Fig. 4 isa top plan view (partlyin section) of the valve stem yoke, and the parts carried byand cooperating therewith-- The present invention-is here shown ap plied-to a multiple cylinder engine, and is especially intended for such-use, though it is I capable of use upon a single cylinder engine;

and it is shown ap lied to a vertically arrangedengine, but t e engine may be-in'any desired position without affecting or departmg from the spirit and scopeof the invenvalve-stems 6 an stems 6 witii tion. A

' l-illustrates atwo cylinder engine, and 1 1n icates the explosiveends of the -cylinders; 2 the inlet valve and'3 the exhaust valve. The valves 2 and 3 are lacedin posiahdthese walls serve to holdthe pins 6 in place in the valve stems. A- spring containmg barrel or thimble .11 is provided with trunnions 12 projecting'from o posite sides and resting in the recesses 13 o ,the yoke'8, whereby the yoke ma work in respect to the thimble as the va ves are reciprocated.

Placed in this spring thimble 14 is a spiral spring 15 with one end resting against the bottom'of the thimble and its upper end resting against the under side of the casing 1.

Projecting from'this casing is a pin 16 which passes through the spring and prevents the springs from buckling, or-lateral movement underthe influenceof the combined tilting and reciprocating movement of {the yoke-8 I as the-valves are worked back-and forth.

Acam shaft 17 is laced belo-wthe valves 2 and 3 and is provi ed with the two sets of cams l8 and 19, the former for-opening-the exhaust valves 3 and the latter for opening the inlet valves 2. These valves are -kept closed through the action of the springs -'15 throu h the medium of the yokes.- When the i et valve '2 is forced open-b its cam 19 (as shown in Fig. 1') one-end o the yoke 1 -8 is moved up against the expanding tension of the spring 15, while the pin 7 of the exhaust valve forms a'fulcrum for the yoke. Likewise, 'when the exhaust valve 3 is opened by its cam 18, the exhaust valve end 0 theyoke is raised while the'op ositeend' thereof is fulcrumed on the pin-o the-inlet valve stem. From the foregoing it willbe observed that asingle sprin lSUtll-lZBdQfOI normally'closing both 't'hei et and exhaust valves, and certain advantages arise in the assemblingcand removal of-the parts which will be pointed out hereinafter. "lieciprocatingheads :or pistons '20 are situated beexpanding springs 25 which serve to normall force the pistons downward or inwar {For the purpose of keeping the pistons from turning in their housings they are 95 tween the'said cams and valve stems, and they move in suitable housings 2-1. Jour-- sufficient to permit the cam-shaft and its cams to be removed endwise, when the bearings 30 are removed. This arrangement permits the cam-shaft with the cams intact to be readily and quicklyremoved without disturbing any other part of the mechanism. Should it be desired to remove any one of the valves, it is only necessary to lift that end of the yoke to unseat the pin 7, push the pin endwise, and the valve can be removed through its screw-plug opening 4 or 5. If desired both valves can in the same manner be removed at the same time, and are readily accessible for that purpose. Also the housings 21 are readily accessible for removal together with their pistons without disturbing any other part. of the mechan- 1sm.-

Having thus described the invention, what we claim and desire to secure by Letters Patent is- 1. The combination of two reciprocating valves having valve stems rojecting in the same direction, removab e pins passing through said stems, a spring yoke having its ends projecting at each side of said valve stems and engaging said pins, the yoke constructed to hold the pins in, place and a spring holding the yoke in engagement with e pins.

2. The combination of two valves having stems rojecting in the same direction, removab e ins passing throu h the stems, a spring *0 e having its en's extendin at each si e of the stems and provided wit recesses constructed to hold the pins against endwise removal, and a spring holding the.

\ yoke in engagement with the pins.

3. The combination of a reciprocating valve having a stem, a removable pin assing through its stem, and a spring yoke aving a recess constructed to receive and re-' vent the endwise movement of the pin w ile in e agement therewith. it:

he combination of a reciprocating valve having a projecting stem, a spring holding the valve closed, a reciprocating iston having an adjustable head adapte to engage said valve stem, and means for mov ing the piston, the parts constructed for the purpose described.
